To aZZwzom it may Concern Be it known that I, WALTER WV. LANGDoN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invent-edcertain new anduseful Improvements in 4Devices for the following is ay specification.

My invention relates to means for soldering ice-cans and `other similar structures composed of galvanized metal or tin.

Ice-cans are expensive to make and only last a comparatively7 short timebefore they commence to rust at their joints around the lower edge or end of the can. I-Ieretofore,

after the cans have rusted in the seams or joints it has been diiiicult to resolder them.

The object of my invention is to provide simple, etlicient, convenient and yeconomical means for resoldering such ice-cans or other structures needing repair.

My invention consists in the construction, combination and arrangement of parts as herein set forth and claimed. My invention also consists in the method employed.

In the drawings:

Fig. 1 isv a side elevation showing thev means for suspending an ice-can in operative relation with a solder receptacle mounted upon a suitable furnace;

Fig. 2 is a side elevation partly broken away of a furnace with solder container mounted thereon and showing the furnace door in open position;

Fig. 3 is a perspective view of the upper end of an icecan;

Fig. 4 is a perspective viewof the lower end thereof;

Fig. 5 is a perspective View of the solderl container; V

F ig, 6 is a section on the line 6- -6 of Fi 1; and

ig. 7 is an'Vv enlarged edge View of rope, pulley and ratchet wheel.

In the embodiment of'my invention as illustrated I provide a frame suitably mounted having a pair of arms 1 eachv having an inturned ear 2 with a verticalhole 3 therethrough to receive and guide the upper ends of sliding rods 4, respectively.

.A cable 5 having hooks 7 is attached at its u per end to eye 8 suitably mounted in an e evated position. The inner ends of said cable are attached to a pair of centrally disposed interposed collars 6 connected byjrigid coupling andeachl collaris y v masia. "UNITE-off STATES? PIA-"TENT vtreff-.iii

provided withyay vertical hole: 10` therethrough in alinement with holesY 3, respectively, to receive and support sliding krods 4. Each slidingrod A4 isprovidedvon its lower vend with knuckle V1 2 to which ltongs 13 are pivotally connected, saidyttongs also having a transverse pivotalconnection .at 11 -thus, permitting saidftongs to move onsaid respective pivots in two directions either toward or from each other or each laterally in the same direction .to permit the hooks 14 to engage or disengage flanges 15 of icecan16., v v

Cable 5 passes over pulley 17- journaled at 19 tbkhanger 18 suitably mountedin an elevated position, thence over groove 33 of pulley 2O j ournaled'at 21 to hanger 22. Rigidly connected to pulley 2O is a ratchet wheel 23 engaging pulley 24 in alinement therewith. Open solder container 25 is removably secured in the open top of furnace '26 with its side langes32 restingv upon and supported by side anges 30 of furnace 26. Door 31a permits access to 'valve 27 which controls thel fuel from supply pipe 28 to burner 29' by which the solder in vcontainer 25 is melted and maintained in'liquid form.`

When it is desired tosolder the lower end suchas 34 of ice-can 16 by means of my invention dip the lower endy of the ice-can; into the hot liquid'solder, then pour into the ice-can a quantity of muriatic acid which will penetrate .the yjoint and eat away the rust. This requires only? about one-half minute. Then remove the ice-can for about'y a vminute to permit the acid to completely eat away the rust. Then dip the joint to be soldered'into theliquid solder-for an instant, :.then draw it out, whenthe Vsolder will cool and set. Each lower edge ofthe can is treated in the same way and this treatment rena comparatively small expense. .j

In order to suspend the ice-,can in proper position to be soldered the hooks 14 are caused to engage flangesl of the can. It

: is then hoisted by means of pulleys 2O and 34 on its inner and outerl surfaces to engage the liquid solder in container 25. A reverse rders the can substantiallyas good fas new at Y g; Lieoie movement of pulley 2O will Withdraw end 34 from the liquid solder and hoist thecan to its initial position.y

What I claim as new and desire to secure by Letters Patent is: I

l. In a device for solderingice-cans, a solder container, a pair of spaced apart arms each having an inturiied ear provided with a vertical hole, a slidingv rod mounted in each of said holes and guided thereby, a lexible'rnember adapted to support said sliding rods, means for raising and lovferingfsaid sliding rods and tongs pivota'lly attached to said rodsto detachably support an icecan, for the purposesfset forth.

2. In a 'device for soldering ice-caw, a pair of upright arms each having an ear provided Witha vertical-hole, sliding,- rods :in transverse directions, and means for raising and lowering said tongs.

3. In a device `i'or solclering ice-cans,- a liquid solder container, iexible Asupporting means, guiding means, .pivotally mounted` tongs adapted to swing toward each otherfto support an ice-can and means for lowering' the saine into said vsolder container `and raising it therefrom,.as specified.
